“…Dissolution of iron in not deoxidized, neutral aqueous chloride solution is a multistage process [20]. Its mechanism can be written as follows: (4) Then the ferrous hydroxide layer reacts with excess oxygen in the solution, to yield the final corrosion product according to reaction: (5) In acid environment the next reaction is: (6) In the case of DLC coated steel the oxidation process was markedly slower (Fig. 4b).…”

“…Amorphous hydrogenated carbon films deposited on steels as protective layers have been used for a variety of applications, including cutting tools and razor blades, and automotive parts, such as piston rings and fuel injectors, etc. [6][7][8][9]. Moreover, DLC coatings with low defect density offer an excellent protection against corrosion because they are chemically inert and impermeable [10].…”

Sliding wear properties and corrosion resistance in Ringer’s solution of uncoated and diamond-like carbon (DLC) coated X46Cr13 steel was tested. The Raman spectra showed that the DLC film was successfully coated by plasma assisted CVD method onto the steel surface. The wear test, carried out using a ball-on disk tribometer, revealed that the DLC coating show better resistance to sliding wear and lower friction coefficient against a 100Cr6 steel ball than five times softer X46Cr13 steel. The oxidation kinetic parameters were determined by means of both the gravimetric and electrochemical method. It was found that the DLC coating markedly decreased the rate of corrosion of the X46Cr13 steel, irrespective of the corrosion mechanism involved.

“…Although the film characteristics depend on deposition parameters, it is well accepted that the higher sp 3 C structures, the higher the chemical resistance. Mansano et al [40] studied the exposure of these films to different acid and alkaline solutions. By means of Raman spectroscopy they observed that only the exposure of a-C:H films to hydrofluoric acid -a reductive acidpromoted a degradation of the sp 3 C-H bonds, and as a consequence, a reduction in the quality of the films i.e.…”

Corrosion and tribocorrosion studies of a TiB x C y /a-C coating deposited on AISI 316L steel have been performed in an aqueous solution of 0.26 vol.% acetic, 0.16 vol.% peracetic and 0.18 vol.% hydrogen peroxide (commercial product Oxonia 1 vol.%). The corrosion current density of the TiB x C y /a-C coating ranges on the same order as bare steel but with a significantly decreasing friction (0.1 vs. 0.6) and wear rate (~10 times lower). The compact microstructure of the coating hinders the access of the aggressive electrolyte to the substrate, preventing the onset of the corrosion attack, while maintaining an excellent tribological behavior in strong oxidant solutions.

“…Several deposition methods have been developed in order to obtain a-C:H films with higher proportions of carbon atoms in sp 3 hybridization (5) . Hydrogenated amorphous carbon films have found many applications due to association of properties such as high density, hardness, chemical inertness and smoothness (6) . In general way they are prepared via plasma techniques including all the CVD and PVD approaches.…”

A Steel alloy (16MnCr5) used for automotive applications (engine components) was chosen as substrate to be covered by DLC films deposited by Plasma Immersion Ion Implantation. This kind of recovery is useful for improve its mechanical and tribological applications, more specific to increase surface hardness and to reduce the friction coefficient (µ). After polished and ultrasonicated, 16MnCr5 substrates were submitted to PIIID procedures for 100 W of radiofrequency power, from atmospheres supplied with 80% of methane and 20% of argon, keeping the work pressure fixed to 5.5 Pascal. Four different deposition times was chosen being of (1800 s, 3600 s, 5400 s and 7200 s). PIII parameters were (-3600 V, 30 µs and 300 Hz). It was investigated the effect of DLC properties over the substrates using Raman Spectroscopy (for Hydrogen content and microstructure analysis), Ultra Micro-Tribometer (for friction coefficient: µ) and Nanoindentation (hardness).
